Features & Benefits

   
• For professional use
• Latexplan No Ammonia is a two-part cement based smoothing compound consisting of a grey powder (part A) containing special cements, graded silica sands and additives, to be mixed with a synthetic rubber latex (part B)
• Can receive light foot traffic after approximately 60 minutes and is ready to receive floor coverings after 4hrs, depending on the ambient temperature
• Very low odour, making it suitable for use in confined and inhabited areas, where working and/or occupation needs to be maintained
• Should not be mixed with any additional latex or water
• EMICODE: EC1 Plus - very low emission
• Smoothing compounds prepared with Latexplan No Ammonia in compliance with the prescriptions present in this technical data sheet are classified as CT-C20-F6 according to European Norm 13813

Application

Preparation of the substrate:

• The subfloor must be clean, structurally sound and free from grease, oil, paint, polish, dust, plaster droppings, surface contamination and any water softenable or loosely adhered materials
• Any remaining adhesive residues should be checked to ensure that they are hard, sound and are not water softenable and have sufficient cohesive strength to receive a levelling compound
• Bitumen residues must be hard and fully bonded to the substrate
• Where moisture sensitive floorcoverings are to be installed, a British Standard approved test should indicate a moisture level of 75% RH or less
• If this level has not been achieved the use of a MAPEI surface membrane will control residual/static moisture in cementitious substrates
• Plywood substrates must be securely fixed in accordance with BS8203 i.e using minimum 6mm external grade plywood or similar
• For gypsum and anhydrite substrates the maximum moisture level should be 0.5% w/w as measured with a carbide hygrometer
• In all cases, no higher than the level recommended by the manufacturer of the floorcovering
• A suitable primer must be applied, such as MAPEI Eco Prim T Plus, prior to applying the smoothing compound to anhydrite or gypsum based screeds

Priming:

• On highly porous and absorbent surfaces, a coat of primer prior to the application will prevent pinholes within the surface, providing a smooth even finish
• Mapei Eco Prim T Plus acrylic primer may be used on all absorbent and non-absorbent substrates
• For difficult and nonabsorbent surfaces use Mapei Eco Prim Grip Plus
• For marine use apply a thin coat of Mapei Eco Prim Marine onto the clean dry surface without leaving pools of primer an the surface
• Allow the primer to dry (35-40 minutes) then apply allow the primer to dry (35-40 minutes) then apply Mapei Latexplan No Ammonia
• Mapei Mapeproof ESM and Mapeproof One Coat surface applied DPMs will only need priming if left for more than 18 hours
• Mapei Mapeproof 1K Turbo must be primed prior to the application of Mapei Latexplan No Ammonia

Mixing:

• Mix 20 kg of Latexplan No Ammonia part A powder into 4.4 kg of Latexplan No Ammonia part B liquid
• The Latexplan No Ammonia part B liquid container should be shaken and poured into a clean mixing container
• The Latexplan No Ammonia part A powder is then added gradually whilst continually stirring with a mixing paddle attached to a slow-speed drill
• The mixed product has a working time of approximately 20 minutes at +23ÆC
• Do not add any additional latex liquid or water
• Do not over mix the products as this may create excessive heat and cause the mixed product to cure too quickly

Application:

• The mixed product is poured onto the prepared sub-floor and spread with a smoothedged trowel to the required thickness in one operation
• Additionally, the use of a spiked aeration roller will ensure a smooth even finish that will not require any further attention prior to the floor coverings being installed
• Latexplan No Ammonia can be applied from featheredge to 10mm, although a minimum 3mm thickness is recommended to provide the optimum absorption for the adhesive, apply at a minimum floor temperature of +5 C or above
• Drying at normal temperatures Latexplan No Ammonia is set to receive light foot traffic after 60 minutes and bonded floor coverings after 4hrs
• N.B. Latexplan No Ammonia will remain a darker colour even when cured after 4 hours

Cleaning equipment:

• All tools and mixing containers should be washed and cleaned immediately after use before the material hardens

Storage & Safety Instructions

• Part A has a storage life of approximately 12 months if stored in dry conditions
• Part B has a storage life of approximately 24 months if stored in dry conditions and protected from frost
• Instructions for the safe use of the product can be found on the latest version of the Safety Data Sheet (see 'Data Sheets' section above)
